The development of an efficient oxidative [2,3]-sigmatropic rearrangement of allylic hydrazides, via singlet N-nitrene intermediates, is reported. The requisite allylic hydrazide precursors are readily prepared and undergo smooth sigmatropic rearrangement upon exposure to iodosobenzene. The products of this novel transformation are shown to be useful precursors to a variety of compounds.
据报道,通过单线态 N-硝烯中间体开发了烯丙基酰肼的有效氧化 [2,3]-sigmatropic 重排。必需的烯丙基酰肼前体很容易制备,并在暴露于碘代苯后进行平滑的σ重排。这种新转化的产物被证明是各种化合物的有用前体。
